A device for wrapping product wrappers including a winder, the winder including a gripper mechanically connected to a tubular shaft rotatable about and translatable along an approach axis, the gripper being rotatable and translatable integrally with the tubular shaft; an actuating rod active on the gripper and movable along an actuating axis, the actuating rod being movable along the actuating axis with respect to the tubular shaft and rotationally constrained to the tubular shaft, wherein the gripper is rotatable and movable following a translation of the actuating rod along the actuating axis; a first electric motor active on the actuating rod to translate the actuating rod along the actuating axis; and a second electric motor active on the tubular shaft to translate the tubular shaft along the approach axis. The device further includes a control unit configured to drive the first electric motor and the second electric motor.

A self-propelled wrapping machine movable around a load to wrap the load with a film of plastic material, comprises a wrapping apparatus, which includes a supporting base, a column fixed thereto and an unwinding unit slidably supported by the column and suitable to supply the film unwound from a reel; and an automatic guided vehicle movable and arranged to be reversibly and automatically coupled to the supporting base in an assembled condition of the self-propelled wrapping machine to support and move the wrapping apparatus around the load and enable to wrap the load with the film.
